Outsourced energy solutions

• Customers are willing to outsource heating and cooling production to energy company• Harms and risks of own production are avoided• DHC are reliable and cost efficient solutions for whole life-cycle• DHC customers can concentrate on their key businesses

DHC Customers

• Customers are buildings or buildinggroups, never separate appartments

• Real estate ownership is concentrated in the hands of major real estate owners

• Voluntary connections to DHC

• No obligations for energy companys to connect every building

• No specific DHC legislation in Finland

90 / 90 / 90 philosophy in District Heat

1) Market share is more than 90 %

2) Share of CHP more than 90 %

3) Overall efficiency is more than 90 %

CHP and DHC in Helsinki• The decisions of CHP and DH were

made in 1953 by City Council

• Basic reasons for the DH were;

• Economical• Ecological• Supply reliability• Energy political

• CHP has been the basic productionsolution from the very beginning

• District Cooling supply started in 1998

• From the beginning DHC has beeneconomically success

Combined Heat and Power (CHP) production• The combined generation achieves high efficiency, in other words more energy is gained from the same amount of fuel

• Combined generation reduces carbon dioxide emissions

• District heating has improved the air quality in Helsinki• Energy efficiency has improved further when District Cooling is produced in the same processes

The amount of fuel saved by using CHP

Used natural gas and black hard coal

Fuel energy, GWh

Fuel saved by using CHP

With CHP, Helsinki saves so much energy compared with separate property-specific heating produced by condensing electricity that it would heat up to 500,000 detached homes each year.

District Cooling

Rapid growth is based on customers own will to choose District Cooling in a free market

Success story from the Finland

District Cooling in Helsinki

• District cooling is expanding rapidly

• It substitutes locally produced cooling

• It saves energy and conserves the environment

• It is produced in an environmentally benign way

• Europes 3rd largest supplier of DistrictCooling

17

Cooling demand in Helsinki

• More than 80 % of production is based on energy that otherwise would be wasted

District Cooling production

• Large primary energy and CO2savings compared to alternative cooling solutions.

The Katri Vala heating and cooling plant

• The plant is the largest in the world to use heat pumps to produce District Heat and District Cooling form both purified sewage water and sea water.

• Its output is 90 MW of District Heat and 60 MW of District Cooling. This is enough to heat a small town.

• The plant is located in a space excavated underneath the Katri Valapark in the district of Sörnäinen
